I am currently running Lightroom 4 on a Mac. I have created a slideshow with images and set "fit to music" with a track from my itunes library. However, whenever I hit the play/preview button the song is distorted and in slow motion. This has been happening a lot lately. Sometimes it will work fine and other times it won't. Any help would be greatly appreciated. I've searched and can not find an answer to fix the issue. And upgrading at the moment is not in the budget. Thanks!
